1. Create docker proxy repo to https://quay.io
2. Create docker group and add proxy repo into it.
3. make this request to group repo:
4. All the connections in the outbound http connection pool for the proxy repo are used by that single inbound request.
The consequence is that this can cause other unrelated requests tags/list docker requests to the remote to fail.
If one examines the outbound request handling, you can see 20 outbound requests of this form - the connection pool size for a proxy repo is 20:
tags/list resource needs to be much more efficient handling outbound paged requests.
